Transition metal single atom-optimized g-C3N4for the highly selective electrosynthesis of H2O2under neutral electrolytes

TM SAs-optimized CNNS have been synthesized for the neutral electrosynthesis of H 2 O 2 . Compared with CNNS, the selectivity of Ni 0.10 SA/CNNS for H 2 O 2 increased from 61% to 98%. The H 2 O 2 production rate of Ni 0.10 SA/CNNS is 503 mmol g cat −1 h −1 .
